Other forms: macros
Macro means made for photographing very small things close up. A macro lens, macro photography, shoot macro.
A true macro lens reproduces the subject at life size or larger on the sensor, which is the technical definition and not merely close focusing. In computing, a macro is a recorded sequence of commands run as one. In economics, macro means the whole economy, against micro. Note that the Greek means long or large, which is the opposite of what the photography sense suggests.
